I don't have actual weights but I can tell you off hand that the G2 is slightly heavier than the Myth. But well worth the tiny bit of weights It adds. The G2 is really the Ferrari of Regulators. If you have any questions at all feel free to PM me
Thanks

I would think that maybe the G2 is heavier, but by literally the smallest of margins. They use the same body, with two differences. One being that the G2 has the additional burst disk, so they mill out the cavity for the burst disk (Which lightens the body a bit), and then add in the burst disk (Which may weigh the same amount at the amount of metal that was taken out for the milling, or, since it is brass and the body is aluminum, may weigh ever so slightly more). Also, the upper part is brass, and an aluminum sleeve, so it should weigh in, technically, a touch bit more. The original Myth would be lighter, but not buy much, maybe a few tenths of a gram or so?

All of our Myths have the 4 Port Design Gauge, Fill Nipple, and both a High Pressure and Low Pressure Burst disk.
